Using an installation-provided filter

For each type of data format (line-data, MO:DCA-P, PostScript, text, PCL, PDF, SAP, XML, and other), you can specify the name of an associated filter. A filter is a program that can inspect and modify data. When you specify the name of a filter for a supported data format in a printer definition, the filter is called when the data format is detected. Print Interface can call the associated filter (a filter is called only once for each data set) before it writes the data to an output data set on the JES spool.

Your installation can write its own filter program, either a DLL filter or a UNIX filter. For information about how to write a filter, see z/OS Infoprint Server Customization.
